We consider a general scheme to construct Bayesian incentive-compatible mechanisms using a suitable ‘variable mechanism parametrization.’ The key idea is to perturb a given direct mechanism, which might not be truth revealing, introducing sufficient variability as a function of agents’ announcements to generate incentives for truthful revelation. We discuss a variable-price auction in a general...

This paper studies a model of product variety with flexible manufacturers when, contrary to prior work, atomistic entry occurs prior to horizontal integration. In this model, more lax antitrust laws that allow for fewer and more concentrated merged firms lead to a greater extent of excess entry. Optimal policy permits no horizontal mergers when demand is perfectly inelastic, but may permit some...

We performed vapor phase filling of SWCNTs with various kinds of fullerenes. C60, C70, C enriched C60 and mixtures of these were used. The resulting peapods as well as the DWCNTs obtained by annealing were characterized with multi frequency Raman spectroscopy. Simultaneous filling with C60 and C70 was found to take place with the same efficiency. When using the C enriched C60 for DWCNT synthesi...

The Cover Feature shows a fullerene molecule included in nanocage constructed from anthracene and triptycene units. strong affinity the supramolecular aromatic complex is attributed to multipoint CH⋅⋅⋅π interactions between cage host spherical guest. showed higher selectivity toward C70 compared C60.

The Enam null mice appear to be smaller than wild-type mice, which prompted the hypothesis that enamel defects negatively influence nutritional intake and bodyweight gain (BWG). We compared the BWG of Enam(-/-) and wild-type mice from birth (D0) to Day 42 (D42). Wild-type (WT) and Enam(-/-) (N) mice were given either hard chow (HC) or soft chow (SC). Four experimental groups were studied: WTHC,...

Fullerenes are reactive as dienophiles in Diels–Alder reactions. Their distinctive molecular shape and properties result interesting sometimes elusive reaction patterns. Herein, to contribute the understanding of fullerene reactivity, we evaluate energies reactions for cycloadditions C60, C70, IC60MA with anthracene (Ant), by means DFT computational analysis vacuum solution. The methods used sh...

Recent low-temperature laboratory measurements and astronomical observations have proved that the fullerene cation + C60 is responsible for four diffuse interstellar bands (DIBs). These absorptions correspond to the strongest bands of the lowest electronic transition. The gas phase spectrum below 10 K is reported here for the full wavelength range encompassed by the electronic transition. The a...
